SWING.

SPECIFICATION forming part of Letters Patent No. 566,529, dated August 25, 1896.

Application filed April 2, 1895, Serial No. 544,136. (No model) To all whom it may concern:

Be it known that I, HANS O'rro OLsoN, a citizen of the United States, residing at Two Harbors, in the county of Lake and State of Minnesota, have invented certain new and useful Improvements in Swings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and to the letters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide a cheap and substantial swing.

It consists in the construction of parts in a combination substantially as below described and claimed.

Reference being had to the accompanying drawings, forminga part of this specification, in which similar letters of reference indicate corresponding parts in all the figures- Figure 1 is afront elevation. Fig. 2 is a side elevation. Fig. 3 is a side elevation as applied to any ordinary chair. Fig. 4 is a detail view, and Fig. 5 is a side elevation showing the swing by dotted lines in its extreme positions.

Referring to the lettered parts of the drawings, y will serve to illustrate the ceiling of a room or the top of some framework constructed to support the swing and from which the hangers H II are suspended. Both of said hangers are hinged at T T to ceiling supports N N. These hangers may be adjusted to any desirable length by means of bolts X X and adj usting-holes I 1.

Seat B rests on brackets J J, secured to hangers H II, which brackets may be raised or lowered by means of holes V V and bolts. Under seat I5 bearings K K are secured, said bearings being provided with notches and resting upon brackets J J, also provided with notches U U. Seat B and hangers II H may thus be kept in place and at any desired place.

Back-rest Gmay be adjusted to any desired inclination to hangers H H by means of extension-rods E. I prefer to make said rods being turned over at a right angle and in- Preferably rods E are secured to the backrest by means of loops and bolts F, the other end of said rods being made in form of a halfcircle and connected to hangers II II by bolts V V and A A. hen I desire to lower the back-rest C, rods E at the same time have to be lowered in proportion. To accomplish this, I have provided a series of holes through which bolts A A may be interposed, hence at all times keeping the back at any desired position.

Seat B is preferably kept at any desired incline by means of adjusting-rods D D, secured to hangers H II by means of bolts M M, and may be raised or lowered by means of a series of holes in the half-circle part of said rods and bolts L L. The lower ends of said rods are preferably extended down underneath seat B at its rear end. Hangers H H also act as guides for brackets P P, to which foot-board O is secured.

Angle-plates R R are preferably hinged to the ceiling supports N N, and may be placed forward or back by means of holes S S. From angle-plates R R cords Q Q are suspended and connect to foot-board O; hence the height of the foot-board may be regulated by shortening or lengthening said cords, according to the wish of the occupant of the chair.

By means of this construction, in connection with the chair and the vertically-moving foot-board or treadle, the occupant, by sitting in the chair and placing his feet against the foot-board, can, owing to the leverage thereby obtained, throw the chair rearward. When the chair moves back past the center of gravity, the heels of the angle-plates will strike against the ceiling supports and stop their travel, which, in connection with treadle O and by means of cords Q Q, causes said treadle to raise. When the swing has arrived at the desired elevation, the treadle is past its normal position, and any further depression on said treadle in connection with angleplates B, R, treadle O, and cords Q Q will give a greater velocity to the swing and bring it past its normal position, when, by releasing the pressure on the treadle, the chair will again seek its normal position by gravity.

By continuing the operations, the occupant of the chair can easily keep the same in a swinging motion and always under perfect control.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a swing, the combination of adjustable hangers hinged to the ceiling supports provided with a series of holes for adjustment; brackets for the swing-seat to rest on secured to said hangers, a series of holes in the hangers for the raising or lowering of said brackets and adjusting-bars secured to the hangers a distance from their centers one end of said bars being constructed in the form of a half-circle and provided with a series of holes through which said bars may be secured to the hangers and placed at any desired angle or position, the other end extending down and projecting under the seat; and adjusting-bars secured to the hangers having one end constructed in the form of a half-circle also provided with aseries of holes for adjustment the other end secured to the back-rest of the swing-seat said bars being constructed in two sections each section having a series of holes and one end bent at a right angle to intersect said holes and a sleeve for keeping said sections in place, substantially as described and shown.

2. In a swing, the combination of adjustable hangers hinged to the ceiling supports and brackets provided with a series of notches secured to said hangers, two bearings pro- 1 HANS OTTO OLSON. Witnesses:
